I would consider making views out of the other queries (then the main query and the joins are simple), but I would also probably change the queries. The usual thing to do is to include everything but the aggregate in the GROUP BY clause, but I'm not sure what MySQL does when you don't do that and I don't know, e.g., what the keys of the tables are or if you have duplicate client name's with multiple client id's and how you want to handle that, etc.
